DRAFT-GEAR FOR GANG-PLOW'S.

Specification of Letters Patent.

Pa-tented Apr. 20, 1920.

Application filed October 18, 1919. Serial No. 831,733.

e yeition object to proide an improved dra: ear for connecting plows witl tra or including a draft a n disposed obliquely to the line of movement of the plows and connected with the tractor in such manner that the plows are caused to make a wide turn the corners of a field 1 thus minimize the unplowed areas at such corners.

With this and other objects in View as wilFappear as the description proceeds the llltlltlOll comprises the novel features of construction. 1ccompanied by elements and arrangement of parts which will be more full described in the following specifi cation and set forth with particulari y in the claims appended hereto.

Figure 1 represents a plan VlQW of the draft gear, and,

Fig. 2 represents a transverse sectional View throu h the draft rod.

g to the drawing in detail wherereference numerals designate cori parts throughout the several views the numeral 5 indicates the draft bar which is provided at equal distant intervals with clips which are preferably constructed of two substantially ii -shaped members 6 arranged in opposed relation above and below the rod 5 and having ei'tended terminals receiving bolts 7 whereby the clip members are rigidly attached to the draft rod. The rear bolts of the attaching clips 6 are pivotally connected with links 9 adapted for connection with the cleyises of the beams of the gang plows (not shown).

Forwardly converging draft bars 10 and 11 are arranged forwardly of the rod 5, the outer bar 10 being connected adjacent one terminal of the rod 5 and the other bar 11 being attached thereto at a point adjacent the center of the draft rod. The front terminals of the bars 10 and 11 are pivotally connected by a bolt 13 and the an ularity of the rods may be varied by selective engaqement of the bolt 13 with any one of a C sei es of apert 12 formed in the forward. GXtFlIllt' of the bar 10.

ii coupling linl:

1% is pii'otally attached to the IOlWEtli terminals of the draft bars and is adapted for in on it icrn iinal with the coupling elelnent tractor shown).

A connecting element 16 in the form of a cable or other flexible member is attached at its rear terminal to the extremity of the l 5 red 5 opposite the bar 10 and is atr at its forward terminal with a relashort chain section the front link of v, nich is of such internal diameter as to receive the coupling bolt of the coupler of the tractor whereby the flexible connecting m illlel 15; attached thereto.

W hat 1 claim is:

1. A draft gear for gang plows including a draft rod, plow beam attaching); clips carried by the rod, draft bars connected adjacent the center and one terminal of the rod an! aflcnible draft element connected with the opposite terminal of me rod and extend forwardly therefrom.

2. A draft gear for gang plows including a draft rod, bars pivotally attached adja cent the center and one terminal of the rod and extending forwardly therefrom in converging planes, an adjustable connection be tween the forward converged terminals of the bars and flexible draft element extending forwardly from the opposite terminal of the draft rod and extending toward the conyergee terminals of the bars.

3. A draft gear for gang plows including a draft roe, plow beam attaching means carried thereby a relatively short draft bar pivotally attached adjac nt one terminal of the rod and extending obliquely therefrom, an intermediate draft bar piyotally connected with the medial portion of the draft rod and extending forwardly therefrom, an adjustable pivotal connection between the first and second mentioned bars, and a flexible draft element connected with the opposite terminal of the rod and extending forwardly therefrom.

In testimony whereof, I my signature hereto.

STANFORD WILSON.
